Varieties of Yellow Pond-lilies can be found across the US.

Why is it possible to drown a common house and yet there are that grow gleefully in water?

The common Yellow Pond-lily has a beautiful bloom and large, heart-shaped floating leaves (nearly 18-inches in length). The bloom is nearly 4-inches and held just above the water surface in spring through early fall.

Survival

The Yellow Pond-lily has developed a specialized type of underwater tissue that helps it survive. This tissue, called aerenchyma, facilitates the underwater movement of large amounts of oxygen and other gasses. This tissue holds eight times the amount of oxygen, compared to a house plant.

Respiration in water lily-type plants is anaerobic (meaning the process occurs without oxygen). Many ponds and slow-moving waters where it grows are often low oxygen. This respiration process creates (a type of ) within the plant’s cells.

This alcohol is poisonous to the plant. To get rid of the alcohol quickly, the plant evaporates it up through the aerenchyma cells and bloom. The pretty yellow blooms smell strongly of alcohol which attract pollinating flies, and create a small bottle-shaped tuber to store sugars in (explains the common European name of ‘Bandy-bottle’).

Medicine

1/2 Yellow Pond lilies have been used in traditional medicines remedies. There are warnings related to and selecting materials from a clean water source (see the Natural Medicinal Herbs website at http://www.naturalmedicinalherbs.net/herbs/n/nuphar- lutea=yellow-water-lily.php).
